Specially scribed transparent plates may lead to λ/100 resolution.

Hank Hogan

Investigators have been searching for the perfect lens, or at least one that can image far below the wavelength of the source light. In addition to being useful in research, such a lens could find a home in semiconductor nanolithography, in increasing the capacity of optical storage disks, or in allowing an inexpensive red laser to have the resolution of a more costly blue one. In this plot of calculated intensity, the focusing of an evanescent field is shown. The interference of neighbors on the central point, marked with a 0, keeps the beam from spreading until the neighbors die away,...Read full article
